Probably would be best to allow your users to change their passwords regardless of it being a Facebook linked account.Better still, make them change their password before continuing if they registered with Facebook.This script allows users (who are registered via Facebook) to use either Facebook connect or a password.Now, since the password is pre-defined, if anyone knew you were using this script and knew which user logged in / registered with Facebook, that person would know the password to be "NaN". Which is why I recommended you either change the pre-defined password to a more complex password or (if you know how) have PHP generate a random one.
